BITUMEN – NDT

Viscosity Grade. Bitumen is graded based on absolute viscosity at 60 ºC or kinematic viscosity at 135 ºC. The SI physical unit of dynamic viscosity is Poise and kinematic viscosity is expressed in CentiStokes.

ASPHALT – Jet Materials

Asphalt. The use of bituminous materials is mainly addressed to roads construction. The asphalt, named also bitumen, is mainly composed by aggregates and binder, with an infinite variation of mixtures.
